USM Settings For Different Size Photo's?

Thu Jan 19, 2006 9:03 pm

Good morning all.

I edit most my photo's at 1024 or 1200 for which a USM of 500%/0.2/0 works really well.

But now some of my customers/newspapers now wish for images to be of a size 3504.

Now my original USM setting when i edit at this size photo seem to do little or nothing to the image. Can anyone confirm a better USM setting for editing in this larger size.

Thanks all.......

You should not be applying any type of sharpening to the entire photo! That's just silly. Just apply the amount of sharpening needed to the area or items needed via a layer mask, using a soft appropriately sized brush. Just build an action and let 'er rip.

Thanks Jeff.

I was using the copy layer then erase tool on jagged areas. A method i picked up here on A.NET. But as the USM seems to have no effect so that method is all but useless.

So you are saying i should do it the otherway round and use layer mask the unsharped image.... Is that right  Smile

There were a couple of links to a very good article about sharpening in this thread. See reply 8.

Quoting LHRSIMON (Thread starter):
500%/0.2/0 works really well.

500% totally kills my photos. I'll maybe make a first pass on the entire image at say 80%, 0.2, 0 then seletive at around 100-120%, 0.4-0.7, 2 after that.

Not that this helps you Simon, but I thought i'd just share that will you all lol

Read the question, Jeff.

0.2 is just too small a radius to do much on a large image - that's why you're seeing little or no difference.

However, 0.3 and anything between 50-250% works very nicely.

Quoting Sulman (Reply 5):
Read the question, Jeff.

Try and understand the answer.....

Using a layer mask, you can make the .2 a 1.5 or more if you like, or use standard sharpening if you want, as you will be "painting" it on at what ever level you desire. Obviously you don't understand the technique.

Yes Simon, duplicate the layer, apply what ever amount of sharpening you want, then hide the layer mask, select an appropriate brush and brush what ever level of sharpening back on to the image in only the places you need it.

Then flatten of course.

Simon was talking about the amount of sharpening needed, as 500/0.2/0 wasn't working for him at this image size - understandable as with such a low radius setting there is going to be sufficiently less edge definition on a larger image USM has less percieved effect.

This isn't telling you anything you don't know, but you didn't answer the question in your first reply, and trying to patronise me is not going to change that.

Cheers

This was my answer in my first reply.......

....and if you understood what I said, then you wouldn't have responded as ignorantly as you are. It is the answer I intended, and you still don't seem to understand that. It's not about how much, or at what radius is set using USM, it's about HOW it's applied. I can't make it any clearer then that.

I have absolutely no interest, or reason to patronize you, give us a break.....
